MSTEST0007: Use test attributes only on test methods

Cause

A method that's not marked with TestMethodAttribute has one or more test attributes applied to it.

Rule description

Test attributes supply metadata or execution policy for a discovered test. They don't declare a test entry point themselves. Without [TestMethod] or a derived attribute, MSTest doesn't use a helper method's test metadata or conditions when it runs tests.

The following test attributes should only be applied on methods marked with the TestMethodAttribute attribute:

• ConditionBaseAttribute
• CssIterationAttribute
• CssProjectStructureAttribute
• DescriptionAttribute
• ExpectedExceptionBaseAttribute
• OwnerAttribute
• PriorityAttribute
• TestPropertyAttribute
• WorkItemAttribute

How to fix violations

To fix a violation of this rule, either convert the method on which you applied the test attributes to a test method by setting the [TestMethod] attribute or remove the test attributes altogether.

When to suppress warnings

Do not suppress a warning from this rule. If you ignore this rule, your attributes will be ignored since they are designed for use only in a test context.

Suppress a warning

If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable MSTEST0007
// The code that's violating the rule is on this line.
#pragma warning restore MSTEST0007

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.MSTEST0007.severity = none
